I'm fairly certain my 920XM is heat throttling, can someone confirm it for me here is part of my ThrottleStop logfile that shows Chipset modulation go to 25% once DTS drops below 5.

What settings are you trying to run and what are you doing to cause this? Can you run the same situation and post a screenshot of RealTemp?

Not sure if i can get a screen shot as i produced the above throttling while running a 3DMark Vantage test. If you know a way i will take the screen shot.

I ran Vantage with RealTemp open in the background and it did LOG a thermal event. Pic Attached.

Maybe since its just the one core dell didn't install the thermal paste evenly?

i have tstop set for TDP/TDC 75/75 with the Alarm set to bring it back to 62/62 when it reaches 1 DST. I have not touched the multipliers other then the 5% increase VIA the BIOS. I also currently am running it with Chipset Modulation locked at 100% so i don't throttle while gaming due to this issue. Any recommendation on a Thermal Paste to use? Also never really looked while i have been in Best Buy but if someone knows if and which types the sell there as i am going out to sea for the next month on Monday so i wont be able to get any shipped to me before that.

i'm personally using mx-3 on my cpu. and ocz freeze for my gpu.

i also suggest getting a cooler. upping the tdp can rise the temps.
also if your not upping the multi, then why use tstop? i don't think it will throttle at stock. especially on the new bios.

The new bios on the M17XR2 wont throttle because they limited the CPU to having only 1 core go into turbo instead of all when using A07 which i am still on. I also use TSTOP because TDP/TDC increase allows all the cores to stay in turbo without throttling due to power restraints.

I totally disagree with Dell using chipset clock modulation to control the CPU core temperature. Someone needs to tell the Dell engineers that the automatic thermal throttling mechanism built into all Intel CPUs is a million times better and more efficient at gradually throttling the CPU while maintaining maximum performance. Clock modulation should only be used when the core temperature is completely out of control and has gone beyond the 100C Intel thermal throttling point and is approaching the Intel designed 125C thermal shutdown temperature.

If these CPUs were allowed to operate as Intel designed them to, they would gradually slow down by reducing the amount of turbo boost and reducing the multiplier further if need be. The CPU is capable of adjusting performance like this over a hundred times a second which allows it to maximize performance without any risk of damaging the chip. If Intel thought the 100C thermal throttling point was too high then they could easily set it lower but they don't.

Why has Dell decided that the manufacturer of this CPU, Intel, doesn't know what they are doing? Intel's throttling scheme is second to none. Dell trying to create their own throttling schemes by using clock modulation has been nothing but a disaster on every laptop they have used this on during the last two years.

In situations where the real problem is an inadequate power supply, at least give users an option to upgrade to a higher rated power supply. Too many users are left living on the edge of throttling as soon as they try to maximize the performance of their laptop.

kqmaverick: All you can do is work around Dell's throttling scheme. You have to avoid triggering clock modulation. Setting a ThrottleStop alarm to lower the TDP/TDC values is a great idea but you need to leave yourself a lot more headroom. DTS=1 is cutting things way too close. An alarm with a DTS setting of 10 would give you a lot more flexibility and would help avoid clock modulation.

Maybe since its just the one core dell didn't install the thermal paste evenly?

The thermal sensors that Intel uses were never designed to be used for 100% accurate core temperature reporting. Some of the temperature variation from core to core is often times caused by the accuracy of the sensors and not related to how the paste or thermal pad was applied. Re-doing the paste is always a good idea but it won't likely get rid of all of the temperature difference you are seeing from core to core.

You need to repaste and/or reduce your TDP. Also, elevating the laptop from the back helps bring temps down by 3-5C. I keep mine on a targus chillpad at all times. But mine also has a CPU retention mod so temps are lower than everyone else.

Man, this just makes me excited to run benchs on dice. I hit 22K+ on A/C, dice will be a lot more efficient.

@kqmaverick, I highly doubt your going to find that the throttling hinders your CPU in real world usage. The vantage CPU bench is very intensive, and a lot of strain on the CPU. I had some throttling as well when I was really pushing the CPU. I have yet to see any during real world usage though.

The thing is i was noticing FPS dropouts playing StarCraft II that reminded me of my old M17XR1 and that when i noticed the Chipset modulating to 25% so i am experiencing it in real world usage, hopefully i just need a repaste to bring these temps back down. Vantage can my CPU to hit the thermal limit even with stock TDP/TDC.

Well i finally got to put some AS5 and my temp's maxed out at 93 im no longer hitting 100 and throttling. The paste Dell had use was very thick and they really had caked it on.

those temps do seem damn high, i just installed a 920XM and ran wprime, it seems to sit around 75c. i reckon its time to get some decent cpu paste

The above was with AS5 though it was on first boot, it hasn't had the 200 hours to burn in. I also have my TDP at 75 and the bios overclock set at 5%.

I didn't think the M17x-R2 had any significant clock modulation issues. Have you done some logging with ThrottleStop and noticed any drop outs to less than 100%?

If you have then you can try turning ThrottleStop on and put a check mark in the clock modulation box and set it to 100%. There's no way to completely disable clock modulation but this helps to monitor for it and reverse it as soon as it is detected. That's better than nothing and minimizes the amount of clock modulation when it is being used.

Nope I sure don't. But even in past systems where my 920xm hit 100C, it never showed signs of clock modulation.

then maybe the clock modulation does not hapens because of heat unless it was aded in a newer bios

we know that dell's unse that trick when they reaches the limit of thier psu

The majority of Dell laptops that are using clock modulation throttling are using this for power consumption reasons. Laptops throttle back before the inadequate power supply reaches its limit and trips itself and shuts itself off. Clock modulation rarely happens because of any core temperature issues.

M15x owners are hitting the clock modulation wall but this doesn't seem to be an issue with the M17x. That's why the M17x had its turbo multipliers restored with the latest bios while the M15x did not.

quick question!

i'm sort of confused with this 920xm. if it can be for laptop use, why is it written in the box as "desktop processor" and comes with a heat sink? or maybe there's a version for a desktop and also for a laptop?

OK, after reading everything about the 920XM, I went ahead and got this from a friend who had the asus that he put the 920XM in, When i picked it up from him I did the "throttle stop"

started at 21,21,21,21 75/75 no voltage change nor do i see where i can do that, but its hitting 89-jumps to 95 then 100...and alarm .....

I'm guessing by the posts time for re paste? Which is the best to use, and can i get it somewhere comp store or do i need to order?

Thanks for the help.

I can not even think of running a benchmark, its getting way to hot, to quick. at idle nothing running while i type this im at 68 degrees...

definitely repaste and keep the back of your laptop elevated so you get nice airflow into the fan intakes

What paste should i use? Can i go get it from Frys?

Or order it? The fans kick on high speed im watching temp and it seems to get off pretty quick, I hope this will solve the issue.

Personally, i've been using PK-1, but they probably don't have that at FRY's so i'd probably go with something like AC MX-4 which is available everywhere

Dell tech guys just replaced my CPU heatsink and such as well as my GPU's which got rid of my throttling problem for GPU's but thats besides the point.

Literally pointless in them changing the heatsink and such on my CPU.......barely helped. They don't even clean off the old paste from the CPU like !!! I was like are you gonna clean it and hes like, not necessary.....so that was kinda dumb

At least it helped my 940xm temps a little bit. Still can't overclock it at all because it gets so hot if i try. On Prime95 stock settings with turbo, it peaks at like 82C. Tried using throttlestop to increase TDP/TDC and it can probably reach 99C if i didn't stop running prime. It wasn't heating up as fast as before they replaced heatsink but still......honestly retarded how they don't clean it when the problem stated was overheating. W/e, at least my GPU's are fixed and i can overclock those babies

yea i probably will eventually. No need right now.

Managed to get my 285m's at 700mhz core furmark stable.

Only weird thing with these new 285m's is theyre a lower voltage than the default while for 2D theyre higher. So for load its at 1.00V instead of the supposed 1.01V and for 2D idle its at .9V instead of .85V. Im not complaining though, high overclocks from what i can find even on a lower voltage.
